Fungicides viz. Propineb 700 g/Kg, Mancozeb 88.23 w/w, Copper oxychloride, Tebuconazole 50%+ Trifloxystrobin 25% , Carbendazim, Propiconazole, Tebuconazole 430 g/L, Fosetyl 800g/Kg completely inhibited mycelial growth of the smoky blight pathogen (Sphaeropsis malorum) of apple. Fungicides viz. Chlorothalonil, Myclobutanil 10% WP, Azoxystrobin, Hexaconazole, Difenconazole, Captan 70% + Hexaconazole 5% WP, Carboxin 37.5% + Thiram 37.5% ,Flusilazolealso restricted mycelial growth but to the tune of 60 -90% without any significant difference. All these fungicides may now be subjected to field evaluation for the purpose of searching effective fungicidal chemical for control of smoky blight canker of apple.
